A Pſalm of Aſaph] Or, for Aſaph, Davids melancholy Pſalm ſome call it, made by him when he was in grievous affliction and deſertion. Out of which he ſeeketh to wind by earneſt Prayer, by deep Meditation upon Gods former favours, and unchangeable nature; and laſtly, by calling to minde Gods wondrous works of old, both in proving, and in preferving his Church and choſen.

Verſ. 1. I cried unto God with my voyce, &c.] I prayed inſtantly and conſtantly, and ſped accordingly. No faithful prayer is ineffectual.
